Bacteria are single celled prokaryotic organisms. Prokaryotic means that they do not contain membrane-bound organelles. In simpler terms, they don't have cell parts within their cytoplasm. Bacteria are classified by their shape- round or cocci, rod or bacilli, and spiral or spirilla. Bacteria may also have long whip-like tails called flagella or be covered with small hair-like projections called cilia. Both structures are used for movement. Bacteria may have a cluster of free floating DNA in its cytoplasm called a nucleoid or they may have additional small rings of DNA called plasmids. Lastly, a bacterium have a cell wall made of a special compound called peptidoglycan which can provide an extra layer of protection from many environmental conditions.
Phospholipids is the answer
The World Health Organization estimates that about 20 percent of all food is lost to food spoilage. Some of the biological, chemical and physical changes that lead to spoilage are preventable by some preservation methods. Spoilage is characterized by a decline in eating quality, resulting in food that is less acceptable to the consumer in appearance, taste, texture or odor. The foods we eat are all derived from living matter making them subject to the natural process of decomposition. Food not only decomposes but it also lost or spoiled by being consumed by creatures other than humans which are rats, mice, flies and microorganisms.
Answer:
The lamp rattles because close resonant frequency.
Explanation:
The phenomenon of increased amplitude is known as resonance when the frequency of a periodically applied force is equal to or close to the natural frequency of the system it affects. When a resonant frequency oscillating force is applied to a dynamic system, the system oscillates with greater amplitude than when the same force is applied at non-resonant frequencies.
Resonant frequencies or resonance frequencies of the system are frequencies when the response amplitude is at a relative maximum. Due to the storage of vibrational energy, small periodic stresses at a resonance frequency of the system can cause significant amplitude oscillations in the system.
Thereforee, the lamp rattles because close resonant frequency.
